Abstract

The Modified Ashworth Scale (MAS) stands out for its simplicity and low cost, making it a widely used tool for the standardized assessment of spasticity, as it quantifies resistance to passive movement. Although its advantages include its usefulness for initial screening and monitoring of changes, it has inherent limitations, such as limited sensitivity for detecting subtle changes and the lack of detailed biomechanical analysis. The objective of this article was to conduct a comprehensive literature review on the MAS to analyze its theoretical foundations, psychometric properties, and clinical applications in physical therapy, with a particular focus on neurological rehabilitation. The search methodology included specialized databases (PubMed, Scopus, and Google Scholar), with publications from 2010 to 2025 in Spanish and English. Controlled and free terms with Boolean operators were used, and rigorous inclusion and exclusion criteria were applied. The review compared the EAM with other tools, such as the Modified Tardieu Scale, biomechanical measurements, and functional scales, demonstrating that its value lies in its complementary use within a comprehensive assessment approach. The literature confirms variable inter- and intra-observer reliability, influenced by the standardization of the procedure and the experience of the evaluator. In conclusion, the EAM is a useful and accessible tool for healthcare professionals, but its optimal application requires integration with functional assessments and objective measures. This combined approach favors diagnostic accuracy, personalized intervention planning, and improved clinical outcomes in patients with spasticity
